Since 2015 of May Dr. Marc Simon has been an excellent care provider for me and his staff has been outstanding with all my health needs. I truly recommend that all his entire office receive a healthy raise to meet the cost of living in Pennsylvania.

I have appreciated my many years under the care of Dr. Simon. He had become a very important part of my life, spending years getting to know my specific health condition, caring for me, and being the one to orchestrate the process of me having my open heart surgery at age 41. He became somewhat like a part of my family. My husband, children and I all knew that Dr. Simon would do his best taking care of me and that we could count on him.

my experience has been great each time I am at the office for an appointment

March 11, 2019

Dr. Simon is always on top of my condition and very knowledgeable as to how to treat my condition. He started me on new meds at my prior apt. and is always looking for new treatments to improve my condition. Even when he has a very busy schedule, he takes time to talk to me and listen without rushing through the appointment. I appreciate that.
